Robot cables, as the name implies, refer to flexible cables used inside robot arms. Such cables must withstand the torsion, bending, and high-intensity motion of multi-joint manipulators or multi-degree-of-freedom machine devices in three-dimensional space. Since robots need to be used in a variety of complex environments, high requirements are placed on the robot body cable's tolerance to continuous torsion, bending mechanical stress, and environmental adaptability. In addition, the performance requirements of robot cables in different components are also different. Generally, they can be divided into robot body cables, mopping cables, and robot internal connecting cables. When choosing a cable model, be sure to select it based on the actual situation and actual needs.
